Substitute into equations and solve:
Solving for T2:
Plug into equation 2 and solve for R2:
220 miles=R2*[380 miles/(R2+40)]
220 miles*R2+8,800 miles=R2*380 miles
160 miles*R2=8,800 miles
Solve for other variables using the two equations or the T and R equations:
T2=220 miles/R2=R=220 miles/55=4 Hr
